SPOILERS ALERT!!!!!!
It's so crazy how YOU made me fond of Joe Goldberg but in the end it made us realize that the killing he was doing to his partners for "love" was insane. When he starts falling in love with someone else he will kill his previous partner to be with his "soulmate."
It's so weird how I found Joe as a charming prince who will do anything to protect "You." In season 5, I don't know how the writer did it but they turned me against him and made me realize that this is a crime that should not be happening to anyone.
Like Louise said,"The fantasy of a man like you is how we cope with the reality of a man like you."
